What does a math function mean?

A relationship between a group of inputs and one output each is referred to as a function.
A function is an association between inputs in which each input is connected to precisely one output.
A domain, codomain, or range exists for every function. f(x), where x is the input, is a common way to refer to a function.
In mathematics, a function is an expression, rule, or law that establishes the relationship between two variables (the dependent variable).

given function f(x) = 2x - 9

f(-1) = -11 ⇒ x = -1 put in function

f( -1 ) = 2 * -1 - 9 ⇒ - 11

f(2) = 5 ⇒ x = 2 put in function

f( 2 ) = 2 * 5 - 9 = 1

f(3) = -3 ⇒ x = 3 put in function

f ( 3 ) = 2 * 3 - 9 = -3

f(-3) = 15 ⇒ x = -3 put in function

f( -3) = 2 * -3 - 9 = - 15
